how i can cll method c# from Javascript

I don't thing it is possible to directly do the stuff you are trying. Server-side function live on server-side and the client-side function love on the client. The only way to get any server-side code to run is to submit the form. ASP.NET unrolls the HTTP headers, unpacks the hidden ViewState variable, re-instantiates objects, and then decides what events to raise based on all of the above.

What you can do is have your Javascript function set a hidden form variable, then do a form.submit().

Then in your Page_Load handler on the server, use the Request object to check for the presence and/or value of this variable, and call the appropriate server-side method.

Hope this helps. I am not an expert but I found this way while searching for your question. If anyone knows any other way please let me know too.

Sounds like you want to know how to talk to server from Javascript.
There are few ways to interact with server side through client side(Javascript):
1. XMLHttpRequest[^]
2. Callback[^]
3. WebService call[^]
4. PageMethod[^]

You can't directly call a code-behind method from javascript because that would be crossing the client side/server side boundary. I would think a workaround would be to set a hidden form variable to inidcate what method you want to call (in the event that there are more than one), and then call form.submit(). At that point, you can probably handle the Request object in the Page_Load method the page that you submitted to, and call the desired method.

thanks for every one
